ABSTRACT:
A method for controlling a drive train of a motor vehicle, to a method for controlling a clutch device, and to a drive train of a motor vehicle, the drive train being operated in a normal load operation, in which the internal combustion engine moves the motor vehicle against the resistances opposing the movement of a motor vehicle, the play in the load direction pre-determined by the rotary direction of the motor output shaft being closed. The drive train (40) operating outside normal load operation is operated under pre-determined conditions in a second operating mode in which a first load is introduced into a drive train section, causing the play at the drive-end of the load introduction point to be closed or to remain closed, the first load being such that it would not be sufficient to overcome the resistances opposing the movement of the motor vehicle in the plane.
